ICE-,GREAM-CARTON FILLER.

Application filed, June 18,1926. Seria1 I To.,116, 833.

My present invention provides extremely simple and highly efficientice cream carton filler and is particularly designed as an improvement on thattype of ice creami carton filler disclosed and claimed in my pending applications, onefiled April 1, 1925,

applicable to devices for filling cartons or d the like with icevcream' or similarplastic substances and, generally stated, the invention consists'of the novel devices, combinatlons of devices and arrangement of, parts hereinafter described and definedv in the claims.

In th manipulation of-ice cream carton 1 ,fillers it is highly important for sanitary reasons that in the use of a deviceto fill cartons'with ice cream the parts thatcome into/contact withthe ice cream be not handled, that is, directly engaged with the hands; and it is to this feature that the present invention isprimarily and successfully directed;

line 3-3 of Fig. 1.; and

-Fig. 4 is aview partlyin section on the line of'Fig. 2, with some parts shown] in full, and showing the device opened up .';In the accompanying, drawings which illustrate a commercial form ofvthe device, like characters indicate like parts throughout the several views.

i. Referring to the drawings:

' The charatcer Aiindicates a cylindrical paper carton filled. with ice, cream a, as shownin Figs. 2 and 3.v This carton is.of

such size that it may be quite freelypslippe'd into a cylindrical metal shell 5 that serves,

as a carton holder. In its lOvveredge this shell 5 1s 'provided, w1th circumferentially spaced teeth 6 in cylindrical arrangementso and both entitled Ice cream: cartonthat they are adapted to cuttheir way readily through a body of ice cream contalne'd in a can or like receptacle." At the base of its teeth the shell 5 is shown, as I slightly contracted to afiord a stop shoulder bottom of the shell 5 in the plane of itslstop shoulder 7. A v V i For co-operation with the shell or carton holder'proper 5 there isa cylindrical cap 90f the same diameter as the shell 5 and of such depth that it will fit over the projecting portion of the carton A when the latter is inserted in the shell 5. This cap 9 has an aXi-allyprojecting stem or bar 1O equip'ped at its outerend with a hand piece '11.- The web of the cap 9 is shown as providedwith several air escape passages formed in upset thimbles 12 which, asshown, are utilized to hold in position a transparent plate 13, such as celluloid, and a thin metal plate 14 The plate 14 and the web of the cap 9are shown as provided with coincidentsight openings 15 so that the op'eratorcan observe when the carton has been filled; The shell ,5 is shown as provided with small air ports 16, which feature is disclosed and claimed: in my prior application Ser.lN0. 55,5I7 more fully identiand the ,former turned, into a position at an angle ,to' the latter so that an empty carton As an important feature of this, invention heretofore referred to in a general Way, the shell 5 and cap 9 are connected in such a wavlthat thetw o may be" separated axially connection is such that the above movements may; be accomplished without placing the hands .in contact with any of the surface thatcomesinto contactwith the ice cream.

In this preferred arrangement, the connection is made by a flat bail or U-shaped lever 17 that loosely embraces thesides of the cap;

9 and is pivotally connected to the sides of the shell 5 by' pivot trunnions 18. The bar or handle 10 of the cap 9 isarranged, to

slide freelythrough a pasage formed in the top of. the bail 17, In its sides the-bail 1? is formed with longitudinal slots 19 and the cap 9, at diametrically opposite points, is

. provided with outwardly projecting studs or lugs. 20 that work freely in the slots 19. The bail 17 is arranged to swing from its vertical position in one direction only, and as shown, this is accomplished by stop projections 21 on the pivoted ends of said bailthat engage with stop lugs 22 on the sides.

The numeral 28 indicates an outwardly spring-pressed latch lever applied to the ihandle'lO and engageable with'the bail through a notch 24 formed in the latter.

This latch lever will serve to lock the stem against upward sliding movements and thus hold 'thefcap vin -working position against the shell 5, as bestshown in'Fig'. l. V In describing the use otthe device, attention is first called to Fig. 4, by reference to which it will be noted that when the latch lever 23 ispressed inward to releasefthecap ,9vfrom the shell 5, the latter maybe slidup ward, and when turned into 1 a horizontal position in the right clirection,fthe'shell 5 will, under the action of gravity, assume an 'uprightposition 'at'an' angle to the stem and axis of thecap and in which position the'car'ton mayjbe applied within the shell or removed therefrom. This, as is evident, may be accompllshed without engaging the handseitherwith the shell 5 or cap 9. \Vhen afilled-cartonisexposed, as shown in Fig. I 4, its upper'edge may be engaged with the hand" and the carton rotated so.as to trim off the ice cream at the bottom of the carton,

"and, of course, the filled carton may then [be readily removed and replaced by an I empty carton.

' v The carton would be placed in the shell 5 when still in the position shown in Fig. l,

and then when the stem 10 and cap 9 are rotated while in an oblique position, the

Swill, under the action of gravity, as- 'sume position in axial alignment with the. cap, and then by taking hold of the bail 17 "the shell 5 may be drawn upward and the projecting end of the carton inserted into the cap. YVhen the cap has been placed against the shell the latch lever 23'will lock the cap to the shell against axial movements. It is important to note that the lugs 20 on theicap 9 holdthe cap and container 5 against oscillatory movements around their common axis when aligned andassembled to' receive the icecream. lfllence, when the deviceflis oscillated as ail-entirety in forcing the same into the cream, there will be noilost'motion andthe container will be given whatever oscilla'tory movement is applied tofthe cap by the manipulation of the operatinghandle.

'Moreover, the cap andthe container will be locked together whether or not a Carton is in position.

Q The device described has, in practice, been foundconvenient and satisfactory for the purposes had in view and, moreover, it is sanitaryin that the cream-contacting parts need not be handled in the filling operation and that the entire device maybe easily washed and sterilized,

Another important factmay'be noted, to

wit: that the cap isguided for true straightline movements on the yoke-like lever and that the said yokelike lever is stopped in a position "with the stem of the cap coincident with the axis 01 the cylindrical container, so that when'the cap isslid on the yoke, it will go into true registration with the container and will freely telescope to the sidesof said containerand slidable on said stem, s a1d yoke 1n.1ts arms having longitudinal slots and saidcapl'having di- 'ametrically projecting lugs working in said slots.

2. An ice cream carton filler comprising a cylindrical container "formed smooth "at its upper edge and provided with teeth at its lower edge, a cutting Wire extending; across the containerat the base of its teeth, a bail l kelever having its arms pivoted'to" thesides of said container andformedlin its arms above its pivot, longitudinal "slots,

a cap of the same diameter as said container, and a stem secured to and projecting axially from said cap and working slidably through said bail-like "lever, said cap having outstanding lugs working in the slots of said. lever, said container having' stops that engage said lever and fpermitthe sameto move on its pivots in one direction only."
